However, the formation and function of pannexin1-based intercellular cell–cell channels in mammalian cells and vertebrate tissue is a question of substantial debate. This work provides robust electrophysiological evidence to demonstrate that endogenously expressed human pannexin1 forms cell–cell channels and lays the groundwork for studying a potential new type of electrical synapses between many mammalian cell types that endogenously express pannexin1.enacceso abiertoMultidisciplinary SciencesMultidisciplinaryEndogenous Pannexin1 Channels Form Functional Intercellular Cell-Cell Channels With Characteristic Voltage-Dependent Propertiesarticle
